8ee8f2a279 Allow building with clang.
XXX __RENAME is currently not allowed for the kernel, so use plain asm.
Clang rejects definitions of builtins, so it doesn't work without.

1239c2bb08 Publish explicit_memset and consttime_memequal in userland libc.
Remove the double-underscore from the userland versions, and do the
weak alias dance instead, now that these are public parts of libc.

ff7cb014e8 PR/47908: Gary Grebus: SHA256_Transform and SHA512_Transform are called
by openssl with unaligned buffers. All other Transforms can handle unaligned
buffers so make these handle them too.

e0ac190e1e Provide explicit LC_C_LOCALE accessor and drop the various NULL checks.
Provide LC_GLOBAL_LOCALE in a way that works with all locale functions.
Merge constant data used by the initial global locale and the C locale.
Drop function call layer for _current_locale() and directly return the
locale reference, not a pointer to it. Use protected access for global
variables, so that libc references can avoid the GOT overhead.

c7dafd4acd Do not use isalpha here, since we explicitly only support the Portable
Character Set as base and in theory a locale could define a ASCII
control character as letter, resulting in negations. Also avoid isdigit
here to give the compiler a better chance of deciding whether an
unsigned compare or a jump table is a better option, both are very
likely better choices than the memory indirection.

magnitude slower than the existing libc version.

44d1b59f26 Make this work on all ARMs but keep the armv6 optimizations. It as fast as
the existing strlen for small string and once strings are 8 bytes or more in
length it starts getting significantly faster.  For really long strings,
compared to the existing strlen, this uses about 1/2 of the cycles for the
non-armv6 version and about 1/3 of the cycles for the armv6 version.
